Germany identifies its first case of new mpox variant

October 22, 2024

Germany has confirmed its first case of the new mpox variant (clade 1b) in a 33-year-old man in Cologne. The patient, believed to have contracted the virus in East Africa, was hospitalized on October 12. The Robert Koch Institute considers the risk to the general German population low, noting transmission requires close physical contact. This case follows Sweden's August detection of the first non-African case. Meanwhile, Norway reported two cases of the less severe clade 2 variant. The current outbreak originated in the Democratic Republic of Congo before spreading to neighboring countries.

Germany has detected its first case of the new mpox variant, marking a significant development in the virus's spread beyond Africa. The case details and broader context reveal important aspects of the evolving situation.

Key Case Details:
1. Patient Profile:
- 33-year-old male
- Hospitalized in Cologne, North Rhine-Westphalia
- Admitted on October 12
- Believed to have contracted the virus in an East African country

2. Variant Identification:
- Confirmed as clade 1b variant on October 18
- This is the new form linked to WHO's August global health emergency declaration

Public Health Response:
1. Risk Assessment:
- Robert Koch Institute (RKI) considers risk to general population low
- Emphasizes transmission requires close physical contact
- Situation being monitored closely with potential for reassessment

Global Context:
1. Outbreak Origin:
- Initially emerged in Democratic Republic of Congo
- Spread to neighboring countries

2. European Cases:
- First non-African case detected in Sweden on August 15
- Norway reports two cases of less severe clade 2 variant

The German case represents a significant milestone in tracking the global spread of the new mpox variant. While the RKI maintains a low-risk assessment for the general population, the case demonstrates the potential for international transmission. The distinction between clade 1b (the more severe variant) and clade 2 (the less severe form found in Norway) highlights the importance of variant tracking and appropriate public health responses based on the specific strain identified.

The situation underscores the need for continued vigilance and monitoring of mpox variants as they appear in new locations, while maintaining perspective on the actual risk levels to general populations.
